Quantum Mpemba effect in holography
Xian-Hui Ge, Shuta Ishigaki, Yu-Qi Lei +1
We investigate the quantum Mpemba effect in a holographic superfluid, in which states with stronger initial symmetry breaking relax faster toward the symmetry-restored equilibrium.…
Chaotic motion of particles around a Schwarzschild black hole in a swirling electromagnetic background
Wenbin Li, Yu-Qi Lei, Xian-Hui Ge
We investigate the particle motion around a Schwarzschild black hole immersed in a swirling Bertotti-Robinson-Bonnor-Melvin background. This spacetime provides a physically well-mo…
Astrophysically Realistic Secondary Spins Trigger Chaos in Schwarzschild Spacetime and Discernible Gravitational Wave Signatures
Dan-Dan Yuan, Jia-Geng Jiao, Yu-Qi Lei +4
Chaos in extreme-mass-ratio inspirals is often thought to require unrealistically large secondary spins, making its astrophysical relevance uncertain. However, we find that chaos p…
Quasi-Normal Modes and Nonlinear Electrodynamics in Black Hole Phase Transitions
Zi-Yu Hou, Yu-Qi Lei, Xian-Hui Ge
We investigate the connection between thermodynamic phase transitions and quasi-normal modes (QNMs) in charged black holes with a positive curvature constant, within the framework…
